| 摘 要： | 用板式电位差计测量电地的电动势和内阻是电磁学实验中的一个基本实验,但实验过程中,往往测量误差很大,甚至测量出电池的内阻为负值,本文从理论和实验两方面分析产生实验误差的原因后,认为此实验的可信度很低,只能作为一种实验方法介绍。作为测量手段则未必合适。

| Abstract: | It is a essential lab. in electromagnetic to measure a battery electromotive force (EMF) and internal resistance with plate-tpye potential difference meter. But a high tolerance always appears in this way, even negative value of a battery internal resistance is measured. Through analysing the reasons of producting the tolerance from theory to lab, it is considered that the level of worth the trust of this lab. is too low. So being a kind of lab. method to let students know is passable, however being a kind of measuring method is not necessarily suitable. |
